Needs to be twice as thick - Aero Precision M4E1 Barrel Nut Wrench

All smirks aside, this attachment would be 5 stars if it was twice as thick. There is too much play when you snap it on a pretty standard 1/2 inch torque wrench. The play can cause you to misalign the teeth and tear up your barrel nut enough to where you can’t get a good bite. Don’t ask how I know. I ended up with two of wrench attachments and stacking them on top of each other on the wrench driver removed the play. Maybe save some material cost by just adding some buildup right around the 1/2 inch opening. Could be improved, but I was finally able to get my M4E enhanced torqued to spec.
